Abstract (en)

A plasma display device is provided which includes: drive circuits which supply, to display electrodes, progressive scan pulses for performing display on display lines of a plasma display panel based on respective display data, or simultaneous scan pulses for performing display based on the same display data with one even-numbered display line and one odd-numbered display line vertically adjacent to each other of the plasma display panel taken as a set, in each sub-frame of a plurality of weighted sub-frames in one frame; a motion detection circuit which detects a motion of an image based on an image signal; and a sub-frame number decision circuit which decides the number of sub-frames in which the simultaneous scan pulses are supplied in the one frame, according to the motion of the image.
